JR Racing RS310 Receiver
 

My JR Racing 75mhz XS3 Synthesized radio stopped working in my 8t.Setup is MM 4s Neu 1515.I swapped my DX3 system and its the receiver or transmitter.When hooked up the MMs fan comes on but the steering doesnt work and the same with the throttle.I opened the RS310 receiver and it was making a faint clicking sound and a red light on the circut board was blinking red.Also the MMs responds with its no signal light sequence.Whats the max voltage on RS310 receiver my bec was set at 6.1 volts.
